Crypto Security Alert: MediaTek Chip Flaw Could Expose Wallet Seeds



Researchers from Ledger discovered a vulnerability in the MediaTek Dimensity 7300 chip that could allow attackers with physical access to extract crypto wallet seed phrases in minutes using electromagnetic fault injection.

The flaw (CVE-2025-20435) may impact Android devices from brands like Motorola, Realme, Oppo, and Nothing, potentially exposing seeds from wallets such as Trust Wallet and Phantom Wallet.

⚠️ Not a remote hack but experts recommend updating firmware and using hardware wallets for stronger crypto security.
